Agricultural technology sharing needs open data. Johannes Keizer presented at a CAAS/GODAN workshop in Beijing about GODAN, which advocates making agricultural and nutrition datasets global public goods and openly available. Open data can help double food production to feed 9 billion people and fuel a knowledge economy. However, challenges include ensuring data is findable, accessible, interoperable and reusable. GODAN addresses issues through working groups and growing its network of 396 partners to advocate for open data.
